It's doing both. I didn't use the skunk2 donut I used one from an ep3is it a grinding or a hissing sound? The s2 alpha headers are notorious for hissing (leaking) at where it connects to the exhaust. I believe it’s from the crappy donut gasket that’s supplied with it
Was I supposed to completely take off the shaft half cover? Cause I put that back onThat’s kind of odd then, I can’t really imagine an exhaust or header causing a grinding noise. I suppose just take a closer look at the whole exhaust system and retighten some stuff here and there. Hissing is always a sign of a leak anyways
O2 extension, the hanger, new donut gasket and exhaust manifold gasketFollowing, doing mine soon. I bought a used Alpha header last year and finally got the full race exhaust to pair it with. Is there any extra hardware I'm gonna have to get since I got my alpha used with no hardware?
